//      GEANT 4 class header file
//
//  G4PhysicsLnVector.hh
//
//  Class description:
//
//    A physics vector which has values of energy-loss, cross-section, 
//    and other physics values of a particle in matter in a given 
//    range of the energy, momentum, etc. The scale of energy/momentum
//    bins is natural logarithmic.
//
//  History:
//    27 Apr. 1999, M.G. Pia: Created, copying from G4PhysicsLogVector 
//    11 Nov. 2000, H.Kurashige : Use STL vector for dataVector and binVector
//    16 Aug. 2011  H.Kurashige : Move dBin, baseBin to the base class
//    02 Oct. 2013  V.Ivanchenko : Remove FindBinLocation method
